<h3>Given system :</h3>
<h3>Solution to the system :</h3>
Substitute the given value of y into the equation -3x-2y=-12
Distribute -2 through the parentheses
Collect like terms
Move the constant to the right-hand side and change its sign
Calculate the sum and divide both sides of equation by -13
Now, Substitute the given value of x into y=5x-7
Multiply the numbers
Subtract the numbers
The possible solution of the system is the ordered pair (x,y)
Answer: 28 Brownies and 38 Cookies
Let say the brownies sold for B amount and cookies for C amount. There were 10 more cookies sold than brownies. If brownies sold X piece then, total sales would be:
Sales: (X+10) C + XB
Total sales is $40. Cookies sold for $0.50 each. Brownies sold for $0.75 each. If you insert it all to the first equation, it would become:
$40= (X+10) x $0.50 + $0.75X
$40= $0.50X + $5 + $0.75X
40= 1.25X + 5
1.25X= 35
X= 35 / 1.25= 28
Brownies sold at 28 pieces. Cookies sold at: 26+10= 38 pieces.
Answer:3.5 pounds or 56 ounces. 4-.5=3.5 pounds
Step-by-step explanation:
Point slope for a poinit (x1,y1) and slope m is
y-y1=m(x-x1)
poiny (4,-4)
slope 4
x1=4
u1=-4
y-(-4)=2(x-4)
y+4=2(x-4)
Answer:
1440
Step-by-step explanation:
How one of my teachers said is 72 time 40 is 2880
and then 2880 divided by 2 is 1440. This is what my teacher said so I don’t know.
